To all whom it may concern:

Be it known that 1, JOHN LOWMAN, engineer, a subject of the King of Great Britain, residing at 36 Ludwick road, New Cross,

1 London, England, have invented a Machine for the Manufacture of Stoppers for Stoppering Bottles, Jars, or other Receptacles or the Like Purposes, of which the following is a specification.

This invention consists of machinery for laterally compressing cork or the like sheets, disks, wads, washers, pads, packing, or layers or the like and inserting the same into capsules, covers, caps, or the like of any suitable material to thereby produce an improved stopper consisting of such cork held in compression laterally or edgewise in its capsule or cover for stoppering bottles or for other purposes.

Machinery according to the present invendisks etc. and, while so compressed edgewise,

will force or place them into their caps, covers, capsules, or holders (all of which I will hereinafter refer to as the capsules) with or without the waxed paper backing or the like backing (such' as heretofore freuently employed in capsuled cork disk bott e stoppering devices) so that the laterally compressed cork thus placed in the capsule will be retained therein and thereby in this The machine for this purpose accordin to this invention is so contrived that it wil act automatically to effect the various operations of, feeding the cork disks etc. up to the point at which they 40 are compressed, of laterally compressing the same, of forcing or placing them into their capsules etc.as well as, if required, fitting a waxed paper backing (or equivalent backing) to said cork etc. and discharge or eject the finished article (stopper) from the machine;

all of which operations are effected by a series of self contained movements operated by power from any suitable source.

The object of laterally compressing the cork disks etc. previous to inserting them into their. metal capsules and holding same 'in this compressed state isto tend. 170101056.

up the grain holes or pores in the cork or compact or compress the latter so as to render the same less liable to-leakage and prevent cork dust falling from the pores into or among the contents of the receptacle.

1 will now describe one form of machine according to the present invention for compressing cork disks and inserting them into sheet metal caps or capsules as follows In the accompanying drawings:Figures 1 to 4 illustrate the construction of the machine. Figs. 5 to 6 illustrate the mode of operation of the special plunger and the coneshaped piece to be hereinafter described. Fig. 7 illustrates the working face of the special plunger. Fig. 1 is a general plan of the machine (which may be constructed of metal throughout) with part broken away to show details of construction. Fig. 2 is a view in elevation looking in the direction of the arrow a Fig. 1. Fig. '3 is a view in elevation looking in the direction of the arrow 6 Fig. 1. Fig. 4 is a view in elevation of the opposite side to Fig. 2 i. c. Fig. 4 is a view looking in the/direction of the arrow 0 Fig. 1-omitting the vertical frame and mechanism for operating the special plunger.- Figs. 5 and 6 are detail ver ical sectional views on an enlarged scale on he line a.a Fig. 1 and on the line bb Fig. 3 illustrating the mode of operation of the special plunger and c0ne-sha ed piece. Fig. 7 is a view of the end face of t e special lunger which engages the cork piece i. e. coking upwards on the line c-c Fig. 5. Figs. 8 and 9 are detail views corresponding to Figs' 5 and 7 showing a modificatlon with re ard to the plunger for the purpose of enabling the machine to compress cork rings or washers instead of cork disks.

1 is a foundation plate resting on legs or brackets or other support sothat the Work may be carried out at convenient height from the ground. T o the plate 1 is securely fastened a vertical bracket or standard 2. of suitable height; projecting from the said standard 2 towards its u per end are two horizontal arms 3 3 furnis ed with bearings 4 4 which carry a vertical spindle 5 terminating at its lower end in a special plunger 6 to be hereinafter described. Upon the said plate 1 is fixed a vertical spindle 7 (Figs. 1 and 2) formin the axis of rotation of a table 8, 9. Central y arranged around the upper plate 8 of the said table and near its circumerence are a series ofholes 8 and 9 varying in number according to circumstances. The distance between the center of the revolving table 8 and the center of'eachof these holes '8 and 9 is equal to that between the center ofthe said table 8, 9 and the center of the special plunger 6 aforesaid-so that each hole are arranged to slide vertically through the said holes 8 9' (Figs. 5 and 6) formedin the top and bottom plates of the table 8 and 9 (see Figs. 2-, 1, 5, 6). At the top of each of the saidhollow spindles 10 is a cup 11 adapt-' ed to receive the holder which may be a 7 metal cap or capsule 12 into which the laterally compressed cork disk is to be forced.

At the bottom of each of the said hollow spindles 10 is a yertically adjustable collar 13 (Figs. 5 and 6) in contact with which is a tappet lever"13 operated by a cam 14 or suitable mechanism in such mani'ier that each hollow spindle 10 and its cup 11 is elevated in turn at the moment when they are brought underneath the special plunger 6 by the rotation of the table 8 9.

The mode of action of the tappet lever 13 may be more readily understood by reference to Fig. 2 as follows:The tappet lever'13 is pivoted at the point l3 to the vertical standard 2 and is provided at its outward end with a weight 13 and spring 13". The lifting action of the said weight 13* and i spring 13 on the opposite or inner end of the said'tappet lever l3 is controlled by the ro tation of the aforesaid cam 14 working on the roller 1 1" attached to the innerend of the tappet lever 13. v

Referring now more particularly to Figs. 5 to 7:15 is a table fixed rigidly to theve rtical standard 2 at asuitable height above the table 8 aforesaid and having a'circular opening located centrally with the longitudinal axis of the aforesaid special plunger 6 and in vertical alinement therewith. In the said circular opening is securely fixed a comtowards the table 8 and rests 'in the cap or capsule 12 at the moment when the cup 11 is ralsed by the action of the tappet lever 13* as aforesaid. The use of the said cone" shaped tube 16 is in conjunction with the special plungerfi for compressing the corkto the vertical spindle 5 before referred to 15 thealoressrfl special plunger 6 which is of I such form and construction that whileit is adapted to force the cork piece tcork disk l etc.) 18 before same through the said conic piece 16 its lower end 6 normally tends to expand to such an extent that it will engage the cork piece at the outer edge of said cork'. l \Nhile this expanded end will enter the l mouth of the conic piece 16 suchexpanded end will bear against the inside w ll of the latter and as it is i'orc l through me said expanded end pieces be forced radially inwards towards one another and thereby this end of the plunger where it is presented to and in contact with he cork will be col.- lapsed or forced centr. y together by the walls of the said conic piece 16 as the plunger is caused to travel through the said conic piece and push the cork piece 18 in advance of it. The plunger end 6 as well as the cork piece 18 are both compressed by the converging side walls of the conic piece 16 until the cork piece 18 has been passed (in this compressed state) into the inclosing cap or capsule whereupon as the plunger 6 is withdrawn the lower end of it 6 gradually exformation) and as it is permitted so to do by the interior walls of the conic piece 16 until its limit of expansion is reached. For ex amp e said special plunger 6 6' may be made :RmWll in Figs. 5 and '7. Conveniently near said special plunger 6 is fixed a tube or container 19 (secured in the brackets 19) for holding the cork disks 18 the bottom of said tube 19 does not reach the level ofthe top 20 of said table 15 and cone-shaped compression-tube 16, by a distance equal to rather more than the thickness of one cork disk but less than that of two cork disks. The brackets 19 are carried by the plungersupportingbrackets 3 and the disk-containing tube is thus supported parallel to the compression-plunger. Sliding underneath said tube 19 and suitably guided is a pushing most cork disk from beneath the said tube 19 aforesaid in which position it is retained by any convenient means such as-thc two flat sprlngs 2222 (Fig. 1) forming spring holding jaws'which laterally engage theedge oi the disk at opposite points. at the required moment maybe imparted to the said special plunger 6 by a cam-operated lever or any other suitable means for example by a rocking bar or lever 23 (Figs. 2 l and 3) which is attached to the, pivot 24 by the link 25. The said lever 23 is connected which is actuated by the elli tical'cam 28 (on the shalt 31) pressing on t e roller 29 secured to the lower end of the said rod 27. By the rotation of the cam 28 the rod 27 is special plur er 6 is forced downwards piece 21 (Fig. 1) adaptedto push the bottomat the point 26 to the connecting rod 27 pands or spreads again (by reason of its ioo over the cone-shaped compression-tube. 16

Vertical movement drawn downwardsand :consequently the through the conic piece 16 (see Fig. 6). The

return movement of the said special plunger is effected by the spring 30 attached to the opposite end of the rock lever 23. The said cam 28 'and also the before-1nentioned cam 14 may advantageously both be mounted. on and secured to a main shaft 31 which is jcur naled in suitable bearings 32 attached to the foundation plate 1. The said main shaft 31 may be operated by any suitable power.

Means for operating the aforesaid pushing piece 21 may be arranged in any suitable manner'advantageously as follows: Referring to Figs. 1 to 4:-'.[he pushing piece 21. is made with a slot 33 (Fig. 1) at one end in which the end of a rocking arm 34 engages. The said rocking arm 34 is pivoted to a downwardly projecting bracket 35 of the fixed lowsz-Referring more particularly to Figs.

table=15 and has a short crank arm 36 secured thereto at about right angles (see Fig. 4).

A tappet lever 37 is pivoted to the vertical standard 2 at the point 37 in such manner that one end of the said tappet lever 37 rests on the crank 36 of the rock arm 34 while the other end 37 is in contact with a cam roller 38 (on the main shaft 31) having a projecting cam 39. It will readily be seen-that on the rotation of the said cam roller 38.the projection 39 will cause the tappet lever 37 to strike the crank 36' of the rock arm 34 thereby actuating the pushing piece 21 in the manner previously described. The withdrawal of the pushing piece 21 is effected by the spring 40 (Figs. 2 and 4) attached to the rock arm 34.

A suitable mechanism for the purpose of intermittently revolving the table 8 9 ste by step around its vertical axis 7 is as fo 1 3 and 4:The pusher bar 41 is provided with a nose or projection 42 adapted to engage in one of the recesses 43 spaced equidistant apart all ronhelthe lower plate 9 of the table 8 9 (see Figs; 1 and 2). This pusher bar 41 is pivoted at 44 to the rock arm 45 pivoted at 46 to the frame of the machine and.

the said pusher bar 41. is normally kept pressed into engagement with one or other of the said notches 43 by means of the spring 47. attached at its other end to the rock arm 45. The pusher bar 41 has an extension piece 41 which is engaged by a rock lever 48 pivoted at 49 to the frame of the machine the other end 48 of this rock lever 48 being acted on by the crank-pin 50 carried on the collar51 fixed to and rotated by the shaft 31 so that it will readily be seen when the crank pin 50 rocks the rock lever 48 the latter operates the extension piece 41 and serves to lift the nose 42 of the pusher bar 41 clear of the notches 43 and table 8, 9, at which mo- 111811131118 extended spring 52 will pull back the pusher bar 41 into about the position shown in dotted lines in Fig. 1 at which point the nose 42 of said pusher bar will engage in the axis 37 as the tappet lever 37 see Figs. 1 and 4. I This hanging lever 55 at its lower end carries a laterally extending adjustable pin or stud'56 which bears against the rock arm 45 whereby the latter is forced (together with the pusher bar 41 pivoted thereto) towards the arrow a: and thereby the table 8 9 is forced round one notch in the direction of said arrow until the end 42 of the pusher bar 41 comes in contact with the adjustable stop 57 carried on the adjustable bracket 58.

The various cams and motions of the machine are so set and timed relatively to one another that the various operations of (a) rotating the tablc'8 9 (b) pushing the bottommost cork disk from under the tube 19 into position over the conic piece 16 (c) forcing down the special plunger 6 6* (d) moving upwards the hollow spindle 10 and cup 11 etc, etc. and all the other parts of the machine as a whole are so arranged as to act in cooperation as will be readlly understood.

The adjustable stop 57 furthermore serves to insure that the ho low spindles 10 and cups 11 register accurately with the conic piece 16 and the plunger 6 as well as serving to arrest the movement of the pusher bar 41 and consequently of the table 8 at the desired position'as aforesaid.

To steady the rotation of the table 8 9 a friction brake may conveniently be providedsuch as the nut 59 (Figs. 2 3 4) screwed up against a spring 60 and a washer 61 pressing against the lower side .of a bearing through which the table 8 is hung. Means may also be provided for feeding the caps or capsules 12 into the on 11 at the top of each spindle 10 for examp e 'a modification of the device above referred to in connection with feeding the cork disks 18 into the cone-shaped guide piece 16 may be employed or any other suitable means or same may be placed in the cups by hand. We may also employ any convenient and suitable device for discharging each said capsule 12 from its cup 11 after the compressed cork disk has been inserted-for example by the lifting and ejecting spindles 62 (Figs. 4, 5, 6,) fitted vertically in each of the said hollow spindles 10 extendingbeneath the bottom thereof and kept down by its own weight. After each cup 11 holding a cap or capsule 12 has passed under the conic piece 16 the rotation of the said table 8 causes the lower end of each lifting spindle 62 to ride up a curved inclined plane 63 whereupon the top of the said spindle 62 forces out the compressed cork lined metal capsule 12 as shown clearly in Figs. 4 and 5. The said cork lined cap sules 12 may be removed from the table 8 by a. curved piece 64 (Fig. 1) attached to the bracket 58 and interposed in the path of travel of said capsules, or by any other suitable means.

The action of the machine as above described .is as follows :The caps or capsules 12 (Figs. 1 4 5 and 6) having been placed in the cups 11 (either by the mechanism of the machine itself or by hand) the various cams I are set in motion by any suitable power as before described. The first motion places any one of the cups 11 of the series (containing a cap or capsule 12) directly underneath the aforesaid special plunger 6.' The said cup 11 is raised by the tappet lever 13 until it is in contact with'the nozzleof the'conical compression-tube '16 aforesaid (as illustrated in Fig. 6). The flat pushing piece 21 (for pushing the cork disks) slides across and underneath the tube 19 containing the cork disks 18 and pushes oneof them 18over the opening in the cone-shaped piece 16 (see-Fig. 5) Where it is retained in npsition by the flat springs 22 (Fig. I) already described; the special plunger 6 now descends (Fig. 6) and engages the cork practically all. round towards its edge and adaptinguts'elf (by reason of its special formation) to the interior of the cone-shaped piece 16 forces the cork disk 18 through the cone-shaped piece compressing the cork laterally (i. e. from its outer edge) as it descends into the cap or ca sule 12 in the cup 11as clearly shown in Fig. 6 aforesaid. The pushing piece 21 now slides back into the original position and the plunger 6 does the like. The spindle 10 with its cup 11 is nextreleased by the tappet lever 13 and falls back to its original position; the rotausher bar 41 now brings the automatic mechanism into use to e'p ect the compressed cork-lined capsule 12 igs. at 5 6) from the cup 11 and remove same from the table 8 in the manner previously described. The table 8 is next turned round by the said pusher bar 41 until the next cup 11 comes under the plunger 6 and the operation is repeated and so on.

steadies the latter while being moved round 7 stgp y s P- .may be desired to back the compressed cork disks with waxed paper or the like disks-21. device for doing so is as follows j of said ile of paper disks approximately level al the time said disks are being picked up for use. Aswinging tubular arm. 68 is provided having a mouth-piece 69 at one The friction brake 61 (Fig. 2) underneath the table 8,- 9,

endand adapted to make close contact with the top-of said stack of paper disks 65 (Fig. 2) while at the other end it is connected with a pump 70 or other apparatus capable of alternately producing in said tubular more or h-ss of vacuum arm 68 a condit or pressure. The said pump 70 is rigidly held in position by fa bracket 71 which is secured to the foundation plate 1 and may be operated by any suitable means-for exy ample by a slotted lever 72 (attached to the pump piston rod 73) which lever 72 is rigidly and to a convenient point on the said tubular arm 68 arod' 80 is secured by the pivot 81 (Fig. 1). The oposite end of the said rod 80 is formed wit a slot 82, and the end a of the rocking arm is'attached to the rod aforesaid by a pin 83 which slides in the said slot 82., By this arrangement the tubular arm 68 remains at rest during the greater part of the stroke of the rocking arm 75 and is only moved when the-pin-83 comes to the end of the slot 82 in either direction. A-roller 84 is pivoted to the frame of. the

machine in such manner thatwhen the tubular arm 68 is moved by the rod 80, the a said arm 68 rides over the roller 84: and its nozzle 69 istthereby first raised and then lowered in the manner now tobe' described.

The action of the above described apparatus is as follows :By the first motion the tubular arm 68 is swung over the tube 66 containing the paper disks 65 and its mouthpiece 69 is pressed down on the topmost disk; at that moment by the outward, stroke of the piston of the ump 7O avacuous ,1

condition is produced inst 1e tubular arm 68 and this said top disk is picked up by the mouthpiece 69 by suction. By this time the pin 83 (Figs. 1 and 2) attached to the rocking arm 75 has traveled to the end of the slot 82 and now moves the rod 80 and conse uently the tubular arms 68 towards the ta le 8.- By the travel of the tubular arm 68 over the fixed roller 84 above 'described the nozzle 69 of the said arm 68 is first raised out of the disk tube 66 (carrying the top disk with it) and at the termination of the stroke is again caused to descend into a cap or capsule 12 in the cup 11* on the table 8 (see Fig. 1) prior to the said ca sule receiving its cork disk. The stroke 0 .the piston of the pump 70 is now reversed whereby the vacuous condition is destroyed andthe paper disk and dc metal capsule 12 on t e tableS. The arm 68 is then swung back and the operation repeated and so on. I

Referring now to the modification shown in Figs. 8 and 9: In these figures means are illustrated for laterally compressing cork rings or washers said cork rings being fed as in the case of the cork disks from a container 19 over the mouth of the conic piece 16 a cork ring 85 being shown in osition in Fig. 8 over said conic iece and he d in such position in any suitab e-manner as for example by the s ring jaws 22 as shown in Fig. 1 tor holding t e cork disks.

In order to support the inner circumference of the cork ring while it is being laterally compressed amovable mandrel 86 is employed located centrally between the inwardly collapsible arms of the s ecial plunger 6, the lowermost end 86 of tiiis movable mandrel normally extending below the lowermost end 6 of the collapsible plunger (see Fi 8) so that on the descent of the plunger 6 the lowermost end 86 of the mandrel first enters the central aperture in the cork ring before compression commences and affords an internal support-all round the inner edge of said cork ring so that as the latter is forced through the conicpiece 16 by the collapsible plunger 6 6 (as in the case of the cork-disks) the cork ring is compressed laterally upon said mandrel. This mandrel 86 is mounted so as to be ca able of independent movement longitudinally with respect to said plunger,for example as illustrated said mandrel 86 may be provided with a collar 86 which fits down upon the shoulder 6 formed inside the hollow u per part of the plunger 6; while a s ring 87 ocated inside said hollow part of t e plunger 6 bears u on said collar 86 and keeps the mandre 86 normally pressed outwards as shown in ig. 8.

At or near the bottom of he downward stroke of the plunger 6 6 the bottom end 86 .of the mandrel 86 encounters a central boss or stud provided in the metal capsule or othercap or cover which is thus provided with an annular channel adapted to receive the compressed cork ring.therein, and retain same therein under lateral compression; and
